The IC-24 is a distinctive and highly popular one-design keelboat class specifically developed for inter-club racing and series events in the Caribbean. Synthesizing the robust hull, keel, and rudder of the renowned J/24 with a newly designed, locally molded deck, the IC-24 offers an economical and accessible platform for competitive sailing. Conceived by Chris Rosenberg in collaboration with St. Thomian sailor and boat builder Morgan Avery, and his father Dick Avery, the IC-24 has quickly established itself as the most prevalent one-design class in the region.

History and Design

The genesis of the IC-24 traces back to a vision in the early 2000s, aiming to create an easy-to-sail and economical one-design racing boat specifically for the Caribbean. This goal was realized by utilizing a "donor" J/24 hull, rudder, and keel, known for their proven performance and durability. A crucial innovation was the development of a new, modified deck, locally designed and bonded to the J/24 hull. This approach allowed for cost-effective construction and refurbishment, providing an accessible pathway into competitive one-design racing. While the concept was developed around 2000, official production of the IC-24, as a modified J/24, began in 2012. Since then, approximately 50 units have been built, with concentrations in St. Thomas and the British Virgin Islands, along with other locations. The standard J/24 rigging is retained, with the primary racing modification being the allowance for a smaller jib.

Sailing Performance and Handling

The IC-24 is engineered for performance racing, drawing on the well-established hydrodynamic characteristics of the J/24 hull. With a sail area to displacement ratio (SA/D) of approximately 20.03, the IC-24 is a lively performer, particularly adept in light air, indicating a design focused on speed and responsiveness. Its ballast to displacement ratio (Bal/D) of around 0.306 provides adequate stability for a racing keelboat, allowing it to stand up to a breeze while maintaining a relatively light displacement. The displacement to length ratio (D/L) of approximately 172.98 further categorizes the IC-24 as a light-displacement boat, emphasizing its design for competitive speed rather than heavy-duty cruising.

Anecdotal reports consistently describe the IC-24 as a "remarkably comfortable, responsive and stable" one-design. Its handling characteristics are generally praised, reflecting the J/24's reputation for balance and a direct feel at the helm, which are essential for competitive racing. The boat's design, including its fin keel and transom-hung rudder, contributes to its agility and maneuverability on the racecourse.

Accommodations and Layout

Given its primary role as an inter-club racing and day-sailing platform, the IC-24's interior accommodations are minimal and highly utilitarian. The focus of the design, particularly with its modified deck bonded to a J/24 hull, is on creating an efficient cockpit and deck layout for racing crews, rather than providing extensive cruising comforts. Consequently, the interior space would typically be spartan, designed for stowage of sails and safety gear rather than overnighting or extensive amenities. The boat's design prioritizes a simple and robust structure for competitive one-design racing in its intended Caribbean environment.
